Hello Rudy,
create a new project (C++ FirstPerson Example) and deploy that on GearVR; start a server on a desktop PC (e.g. UE4Editor.exe GearFP.uproject ?listen -game -log) wait for it to start up, finally launch the project on GearVR (developer-mode activated) open console by tapping with four fingers on the touch screen and type open SERVER_IP, hit OK and that’s the point where everything crashes
